The Schedule referred to inthese LetteruPatent and making part of the same.

To all to whom these presents shall come Be it known that we, JAMES WALMSLEY and THOMAS WALMsLEY,-of Blackburn, in the county of Lancaster, Kingdom of Great Britain and Ireland,

' have invented certain Improvements in Machinery or Apparatus for Warping and Beaming Yarn; and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known, and of the usual inanner of making, modifying, and using the same. Y

The object of our said invention for certain improvements in machinery or apparatus for warping yarn is, by the application andluse of apparatus hereinafter described and shown by drawing, to arrest the motion of such machinery when a thread breaks or when the yarn is warped or wound o one or more bobbins, or from the cops as the latter may be used in connection with this machine, and thus avoid or dispense with the cost and labor of winding from the spool to the bobbn, as heretofore practiced.

Description of the Drawing. At Figure 1, sheet l, is shown end View of machine constructed according to our invention, and

Figure 2, a front view. ac is the yarn or threads passed over and supported hy the rods b b, thence through the eye of the hooks c, which are hinged or work loosely on the rod (l, over the roller e, throughthe reed eI to the yarnbeam e2.

On the shaft f are the tst-and-loose drivingpulleys 1 Z Fixed to the rim or arms of the fast pulley f1 are four pins or studs, two of these, g y, are longer, and placed, as shown, a little nearer the center of the pulley than the other two, gl g2.

As theepulley revolves the pins y g come in contact with and force apart the levers h h1, working on the stud h2, the upper ends of these levers being in like manner separated or removed further apart from each other.

The motion 'of the lever his, by means of the link and crank 7c, transmitted to the vertical rod l, on which and a like rod, Z1, on the other side ofthe machine, are arms l2 with pins l, ou which arms the crossrails m m' rest.

These rails are, by the motion of the vertical rods Z l1, brought parallel with and immediately in front of the hooks c.

When the stud h2 passes the horizontal or central line, the lower end of the lever h will, by gravitation, or by means of the spiral spring u, close the link and crank k, imparting a partial rotation to the vertical rod l, and a lateral or sidewise motion to the rails' lml m. 1

The upper cud` of the lever h will also close, and the pin 1) thereon `will tilt or raise one end of the catch lr, working on a pin attached to 4the spring-stop'handle s, (seeFigure 3, sheet 2,) clear ofthe pin p on theupper end of the lever h1, which lever and pin is, by the action of the studs g1 g1, caused tomove out ward or further apart from the lever h; so'long as the yarn continues perfect, the'v motions above described are repeated each half-revolution of the driving-shaft, or as often as the studs y g act on the lever h and the studs g1 gl act on the lever h1. n

When a thread breaks, the hook c, through which it was passed, at once falls on the rod w, and prevents the lateral motion of the rail m and partial rotation of the vertical rod l; the lever h being thus held zsta.-v l

tionary, prevents the pin p, on the upper end thereof.v tilting or raising the catch; the study1 will move dipush out the lever h; the pin p', on the other end thereof', taking the catch Tand drawing it and the spring-handles out ot' itsnotch, transfers theJ strap from the fast .to the loose pulley, at the same, time the rod w raises the hook c clear ot' the rail m, and the motion of the machine is arrested. 4-

When the broken end is tied up audvlthemachine started again, by the attendant forcing the springhandle into the position' shown at iig. v'2,the link :t

moves the rocking-bar x1, (supported at each end by brackets,) and by means of the pin the' upright .'v is raised, causing the arms -x er to move on the studs x5, and the rods w are lowered to the position shown at iig. 1.

-Vhen a thread breaksnthe action of the handle s, link x, rocking-bar x1, and finger x2, together with the spiral spring :r2-fig. l, raises the said rods w, on which the hook c of the broken threadrests.'

at* is the faller or drop-rod, for maintaining the necessary tension on the yarn when the machineis stopped.

ai are the guides for the rod. Y

Figures 5 and 6 are elevation and plan views of part of a creel for warping from the cops.

A A are cop-skewers, arranged in the movable frames B, the yarn from which is passed-over the rods C C, and through or around the bars D D', as shown.

E is a swing-rod, resting onor against the yarn so as to maintain theA necessary degree of tension.
